RZR 900 - 50'' Trail Models Shock ? September 7, 2015 Ok so I’m sure this has been asked and I’ve been cruising around the forums for awhile before actually signing up. But do stock and aftermarket 900s socks fit the trail and base 50 model without any modification? Any help would be appreciated Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
